SiS BETA Fuel Gel is a high-carbohydrate energy gel designed for endurance athletes tackling long training sessions and races. Each 60ml sachet supplies 40g of carbohydrate, helping runners, cyclists and triathletes organise a higher-carbohydrate fuelling strategy without carrying as many individual gels.

Its dual-source formula combines maltodextrin and fructose in a 1:0.8 ratio, developed for carbohydrate intake during prolonged exercise. Compact and easy to use on the move, BETA Fuel Gel is particularly suited to events lasting over two hours and can form part of a planned intake alongside sports drinks or other energy products.
